13X沸石去除废水中镍离子的实验研究

Experimental Study on Property of 13X-Zeolite Molecular Sieve:Removing Nickel from Wastewater

实验着重研究了合成 1 3X沸石分子筛吸附重金属离子中的镍离子。结果表明 :当废水pH≥ 5 ,CNi2 + ≤ 2 0 0mg/L ,吸附时间为 30min ,按镍 /沸石质量比为 1∶50投入沸石进行处理 ,镍离子的去除率可达到 99%以上。处理后废水均达到工业排放标准。

Adsorption of Nickel ions in wastewater on 13X-zeolite has been studied. It is showed that removal of over 99% can be attained under optimum condition.
